Cersei Lannister

Eldest daughter of Lord Tywin Lannister of Casterly Rock, Cersei is twin to Ser Jaime Lannister, the Kingslayer. Blonde, green-eyed, and one of the most beautiful women in the Seven Kingdoms, she has the Lannister pride and the ferocity of the mother lion when her children by King Robert are endangered. Her marriage to the king is loveless—a political marriage only, to secure her father’s allegiance after Robert won the Iron Throne—and their conflicts can be brutal. Her brother Jaime is often by her side, serving as her sworn shield as one of the knights of the Kingsguard. Her other brother Tyrion, however, is an affront to her sensibilities, and she denigrates the Imp mercilessly.
